Tooth Preparation: Reduction or Adequate Restorative Space

Most dentists discuss tooth preparation for indirect restorations and use the word "reduction". Did we under-reduce or over-reduce? This paradigm works pretty well when you are doing single crowns in the posterior and recreating the existing size and shape of the pre-operative tooth. But as soon as we get to more complex preparations like inlays, onlays and anterior restorations the paradigm breaks down. It's important to understand the amount of space required for the specific material. In many restorative cases we are changing the tooth size and shape post-operatively. Preparing a tooth while focused on reduction will result in inaccuracies when working from additive or reductive wax ups. In this webinar we learn how to determine the amount of space needed for different restorative materials, as well as increased preparation accuracy.
